Thing is, Brian did very little press from 92-95. And celeb media was very different then. I don't recall him ever being pressed on the point.
BW isn't always great at taking responsibility.
I didn't see/hear ANYTHING about Brian after the separation from Landy, until early 1995, when the Don Was film was mentioned in Rolling Stone. Honestly, without Landy and his team around to supervise Brian, I expected the worst - back to the old drug and booze habits. When I saw his interview in The History of Rock 'N' Roll that spring, I was not surprised to see he had gained weight, and seemed as spacey as ever. Seeing him in IJWMFTT relieved my fears for the most part. He seemed more coherent - for the most part - than he had in the Primetime Live interview, and there was finally the promise of new music from him again.
Carl in the 90's remains a puzzle. As far as I can tell, he may have been working on Like A Brother around the same time as SIP, so maybe he was just resigned to the BB's being Mike's band, and any creativity for himself would have to be put into outside projects. You can only fight the uphill battle for so long before you just get worn down, and I think that's how he felt in the 90's. The Beach Boys had become, for better or worse, "America's Band", the traveling jukebox of sun, surf and sand, and the only thing he could do was at least make sure the music was played properly, the way it was supposed to be.
